Layers of the Earth

WALT: Make a model of the four layers of the earth out of play-dough


So.... that when we learn about natural disasters we can use our knowledge
of the layers to understand them better.


To....help us in topic and science and learn about the earth around us.

Crust:
The crust has about 7 tectonic plates outside of the earth and it’s about 15 - 75 km thick.

Mantle:
The mantle is two different types parts, those are the upper mantle and lower mantle. The lower mantle is 2300km dense thick. The upper mantle is 400 km thick and that is also includes iron.

Outer core:
The outer core is 2300 km thick and it’s iron, nickel and sulphur. It is made out of liquid.

Inner core
The inner core is 1200km thick and it is iron,nickel and sulphur.
The temperature is 6650 degrees Celsius! It is really hot under ground!
